Fostex 10cm cone type full range unit FE108NS

---------------------------------------------------------------------- The two-layer papermaking technology is our own technology that maximizes the capabilities of the materials used. In the FE-NS series, long fiber pulp is used as the main material for the base layer, providing sufficient thickness and internal loss. Short fiber pulp is blended into the surface layer to increase the propagation speed of the diaphragm surface. This enables the reproduction of crisp high tones and thick low tones with good attack while maintaining the bright and taut tone of the midrange. A large ferrite magnet is used in the magnetic circuit to ensure sufficient magnetic flux density. Copper caps are added to the poles to reduce current distortion, resulting in powerful music playback and improved sound quality in the mid- and high-frequency ranges. A high-rigidity aluminum die-cast frame is used to support the large ferrite magnetic circuit and eliminate unnecessary resonance. To improve linearity, a corrugation damper is used that has high compliance and excellent movement with little change in hardness from small input to large input. In addition, a three-point adhesive method is used to bond the cone paper, damper, and voice coil at the same place. By increasing the strength of the cone neck, high-frequency characteristics are improved. The input terminals use Faston 205 type low-loss gold-plated terminals, which ensure a secure connection of the speaker cable and prevent deterioration of sound quality. The FE108NS is a newly developed full-range speaker unit that inherits the development philosophy and unique technology of the Sol series. The well-balanced low range and high-quality mid- and high-range sound quality are supported by a two-layer papermaking and low-distortion ferrite outer magnet type magnetic circuit, realizing delicate and expressive music reproduction.
